科技英语教案大学英语读写四教案③宏观量子隧道效应宏观量子隧道效应是指纳米粒子的一些宏观量(如磁化强度)具有贯穿势垒的能力。
这一效应限定了磁盘、磁带等存储介质的存储时间极限,因为它不但是未来微电子器件的发展基础,也是其进一步微型化的极限。
例如,在制造半导体集成电路时,当电路的尺寸接近电子波长时,电子将通过隧道效应而穿透绝缘层,使器件无法正常工作。
因此,宏观量子隧道效应已成为微电子学、光电子学中的重要理论。
“Targeting Drug Delivery System”靶向给药系统或称靶向制剂,诞生于20世纪70年代,是指这种制剂能将药品运送到靶器药物通过局部或全身血液循环而浓集定位于靶组织、靶器官、靶细胞的给药系统官或靶细胞,而正常部位几乎不受药物的影响。
①Targeted drug delivery, sometimes called smart drug delivery,[1] is a method of delivering medication to a patient in a manner that increases the concentration of the medication in some parts of the body relative to others.②The goal of a targeted drug delivery system is to prolong, localize, target and have a protected drug interaction with the diseased tissue.③The conventional drug delivery system is the absorption of the drug across a biological membrane, whereas the targeted release system is when the drug is released in a dosage form.④The advantages to the targeted release system is the reduction in the frequency of the dosages taken by the patient, having a more uniform effect of the drug, reduction of drug side effects, and reduced fluctuation in circulating drug levels. The disadvantage of the system is high cost which makes productivity more difficult and the reduced ability to adjust the dosages.⑤There are two kinds of targeted drug delivery, active targeted drug delivery, such as some antibody medications; and passive targeted drug delivery, such as the enhanced permeability and retention effect (EPR-effect).⑥Delivery vehiclesThere are different types of drug delivery vehicles, such as, polymeric micelles, liposomes, lipoprotein-based drug carriers, nano-particle drug carriers, dendrimers etc. An ideal drug delivery vehicle must be non-toxic, biocompatible, non-immunogenic, biodegradable and avoid recognition by the host's defense mechanisms.Liposomes are composite structures made of phospholipids and may contain small amounts of other molecules. Though liposomes can vary in size from low micrometer range to tens of micrometers, unilamellar liposomes, as pictured here, are typically in the lower size range with various targeting ligands attached to their surface allowing for their surface-attachment and accumulation in pathological areas for treatment of disease. The most common vehicle currently used for targeted drug delivery is the liposome. Liposomes are non-toxic, non-hemolytic and non-immunogenic even upon repeated injections; they are biocompatible and biodegradable4.Text comprehension ( 35 minutes)Ask the students to read the text and discuss the following questions.1)What did NCI announce?Tips: (Para.1) nanotech solutions to cancer2)What is nanotech?3)Why does it hold promise for cancer detection and therapy?Tips: (Para.2) Size and function.Targeted Drug Delivery System4)What are the delivery vehicles for cancer detection?Tips: two kinds of nanoparticlesnanocrystals of iron oxide (Para.3-5)quantum dot-probes (Para.6-8)5)Please find out the related researchers and the discoveries of their research.Tips:Nanocrystals of iron oxide:Researcher: Jinwoo Cheon, a chemist at Yonsei Universary in Seoul, South Koreareported in the Sept. 7 Journal of the American Chemical SocietyHis report: It can make MRI pick out smaller tumors (Para 3-4); An experiment.

Unit 1 Sources of EnergyText APetroleumSentence structure analysis1. Instead of originating in accumulating woody matter, petroleum may be the product of theaccumulating fatty matter of ocean organisms such as plankton, the myriads of single-celled creatures that float in the surface layer of the ocean. (Para.2) 石油,并不是来自于逐渐积聚的木质物质,而可能是来自于逐渐积聚的海洋生物的脂肪物质。
比如浮游生物:大量浮游在海水表层的单细胞生物。
这是一个简单句,主语petroleum,谓语动词may be,表语product,构成句子主干。
instead of 介词短语作状语,such as plankton是product一词的同位语,the myriads of single-celled creatures that float in the surface layer of the ocean是名词性短语,做plankton的同位语。
2. It is only necessary that the organisms settle down into the ooze underlying shallow arms of theocean under conditions of oxygen shortage. (Para. 3) 生物有机体只需在缺氧的条件下沉积到海湾浅水处的淤泥里。
该句的框架为:it is +adj.+that从句,it做形式主语,真正的主语是that从句的内容。
现在分词短语underlying…做后置定语修饰ooze。
Toward the end of the nineteenth century, however, engines were developed which were powered by the explosions of mixtures of air and inflammable vapors within the cylinders. (Para. 9) 然而,到19世纪末人们研制出了内燃机。
内燃机是通过在汽缸里将空气与可燃气体混合,产生爆炸来提供动力的。
该句为复合句,句子的主干为engines are developed, which 引出的定语从句修饰现行词engines;toward the end of the nineteenth century介词短语作时间状语。
Such internal combustion engines are more compact than earlier steam engines and can be made to start at a moment’s notice, whereas steam engines require a waiting period while the water reserve warms to the boiling point. (Para. 10) 这种内燃机与蒸汽机相比,机身小巧,可以瞬间启动;而蒸汽机需要一定时间,等待储水加热到沸点。
该句是由whereas连接的并列句;在前一个分句中包含and连接的两个并列成分,而后一个分句中包含while 引导的时间状语从句。
5. There is another complication in the fact that petroleum is not nearly so evenly distributed ascoal is. (Para. 15) 还有另一种复杂情况,即石油的分布不如煤的分布均匀。
该句的主句是There is another complication in the fact,that引导的是同位语从句,补充说明fact的内容。
6. Kuwait, for instance, which is a small nation at the head of the Persian Gulf, with an area onlythree-fourths that of Massachusetts and a population of about half a million, possesses about one-fifth of all the known petroleum reserves in the world. (Para. 16) 例如,位于波斯湾岬角处的科威特,面积只有麻省那么大,人口只有50亿,却拥有世界已知石油储量的1/5。
该句为简单句,主语为Kuwait,谓语possesses, 宾语about one-fifth of all the known petroleum reserves in the world。
for instance为插入语,举例说明;which is a small nation at the head of the Persian Gulf是一个由which 引导的非限定性定语从句,修饰先行词Kuwait;介词短语with an area only three-fourths that of Massachusetts and a population of about half a million做后置定语同样修饰Kuwait一词。
参考译文课文A石油1油,和煤一样,存在于沉积岩中,而且可能由死去很长时间的生物有机体形成。
含有石油的岩石几乎都来源于海洋,所以形成石油的有机物一定是海洋生物,而不是树木。
2 石油,并不是来自于逐渐积聚的木质物质,而可能是来自于逐渐积聚的海洋生物的脂肪物质。
比如浮游生物:大量浮游在海水表层的单细胞生物。
3 有机物的脂肪物质主要由碳氢原子组成,因此并不需要太多的化学变化就可以形成石油。
生物有机体只需在缺氧的条件下沉积到海湾浅水处的淤泥里。
其脂肪不是分解腐烂,而是逐渐积聚,并在深层的淤泥里圈闭起来,进而经过细微的原子重组,最终形成石油。
4 油比水轻,呈液态,会经由上方覆盖的孔隙性岩石向上渗透,在地球上有些地区到达表层,古人将这些表层石油称为pitch, bitumen, or asphalt. 在古代和中世纪,这些石油油苗常被看作药品而不是燃料。
5 当然,表层的油苗数量很少。
而石油油藏上方有时覆盖的是非孔隙性岩石。
石油向上渗透抵达该岩石,然后在岩石下方逐渐积聚形成油层。
若在上方的岩石上钻个孔,石油就可以通过该孔向上迁移。
有时压力过大,石油会向高空喷出。
1859年在宾夕法尼亚州,由埃德温得雷克成功打出第一口井。
6 如果可以发现一个合适的地点(勘探人员已经识别出地下可能圈闭有石油的地层结构),那么就很容易抽取这一液体燃料,这要比派人到地下把大块的固体煤炭砍成小快要容易得多。
而且一旦获得石油,可以通过地上管道运输,而不必象煤一样,由运货车经过繁重的装卸任务来运输。
7 石油便于抽取,易于运输,促进了石油的应用。
石油可以蒸馏成不同的馏分,每种馏分均由特定大小的分子组成,分子越小,该馏分就越容易蒸发。
8 到19世纪下半叶,最重要的石油馏分是由中等大小的分子构成的煤油,它不易蒸发,被用于照明。
9 然而,到19世纪末人们研制出了内燃机。
内燃机是通过在汽缸里将空气与可燃气体混合,产生爆炸来提供动力的。
最便利的可燃气体是汽油——石油的又一馏分,由小分子构成,容易蒸发。
10 这种内燃机与蒸汽机相比,机身小巧,可以瞬间启动;而蒸汽机需要一定时间,等待储水加热到沸点。
11 随着各种带有内燃机的汽车、卡车、公共汽车、飞机等交通工具的使用,对于石油的需求激增。
房屋不再用煤,而用燃烧燃料供热;轮船开始使用石油;电力也由燃油提供的能量来供给。
12 在1900年,来自石油的能量只是煤的4%,二战后,由石油的各种不同馏分提供的能量已经超过煤所供给的能量,而现在石油成为推动世界科技发展的主要燃料。
13 石油相对于煤的便利却被另一个事实所抵消:地球上石油的数量比煤少得多。
(这不足为奇,因为地球上形成石油的脂肪物质,要比形成煤的木质物质少得多。
)14 还有另一种复杂情况,即石油的分布不如煤的分布均匀。
世界上的主要能源消耗国有足够的煤,却严重缺乏石油。
美国有世界石油总储量的10%,数十年来一直是主要石油生产国。
现在亦是如此,但是美国大量消耗石油产品,使之成为石油进口国,对于这一重要资源不得不日益依赖其他国家。
俄罗斯石油储量和美国相近,但消耗的少,因而可以成为石油出口国。
15 地球上已知的石油储备约有3/5集中在阿拉伯国家。
例如,位于波斯湾岬角处的科威特,面积只有麻省那么大,人口只有50万,却拥有世界已知石油储量的1/5。
16 由石油而引发的政治问题已经变得至关重要。
Text BThe Future of Alternative EnergySentence structure analysis1. The cheaper rate is still more expensive than the average national price of electricity, which in2003 was a little over 8 cents per kilowatt-hour, according to the U.S. Department of Energy’s Annual Energy Review.(Para. 9) 即使略微便宜的光电价格仍然高于全国电价的平均价格,据美国能源部发行的《能源周刊》统计,2003年每千瓦时的电价均价略高于8美分。
该句包含一个比较状语从句和一个非限定性定语从句,介词短语according to…做状语表示补充说明。
2. Other recent advances include thin film photovoltaic technology, a high-tech coating thatconverts any surface covered with the film into a solar-electric power source. Boats and RVs that use the film are now on the market. (Para. 10) 其他最新的发展包括薄膜光电技术,这种高科技的涂层能够将任何覆盖此类薄膜的表面转化成一种光电电源。
